I have longer than stock plug tubes and this works great. I attached a magnetic dial indicator on the valve cover and was able to use that to determine a very accurate TDC using this tool. I lost TDC by cranking the engine with the distributor out and the new fluidampr doesnt have marks that line up with stock timing cover. Soo this is the perfect tool along with a dial indicator so you dont need to pull a valve cover. just look inside the cover with the tube out with a flashlight and watch for the intake valve to open, once it shuts the piston should be on the way up. screw in the tool and set up your dial, you may need another set of eyes. once the dial stops moving you have TDC, mark your damper and go in reverse and mark. TDC is in the middle of both marks which likely wont show a difference (you can see a difference with a large degree wheel) the damper is too small. no big you are trying to set initial timing which isnt super picky on a street rod. get it close to 10 degrees at idle and you are good to go. ### ⭐⭐⭐⭐⭐ Pretty simple and exactly as described *by S***S on Reviewed in the United States on May 30, 2018* Pretty simple and exactly as described. Place isn’t in the cylinder turn the motor until you are on the compression stroke. When it stops going up you. Have top dead center. I can see how some people say you can use it on engines that don’t have hemispherical heads but I think that is being risky with both the engine and the tool. ### ⭐⭐⭐⭐⭐ Very Useful *by M***L on Reviewed in the United States on July 11, 2011* When your timing belt breaks and you need to find your top dead centre (tdc) of a particular piston, you use this tool. As you rotate the crankshaft, with this screwed into the spark plug socket of the cylinder your looking at, it rises and falls. Its highest point is the tdc for that piston.It did its job, and helped me get my car back on the road. Its permanently in my toolbox. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/7270261-innovative-products-of-america-7886-10-5-long-top-dead](https://www.desertcart.tn/products/7270261-innovative-products-of-america-7886-10-5-long-top-dead) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-20*
